Knee is a hinge joint where the lower leg bone tibia meets the thigh bone femur. During osteoarthritis, cartilage or ligament defects and degenerative arthritis, knee replacement surgery is recommended world-wide to get relief from extreme pain. Knee replacement surgery, also known as knee arthroscopy, is a surgical procedure, in which the affected knee joint is replaced with synthetic material. The most likely candidates for total knee replacement are the patients with severe destruction of the knee joint coupled with progressive pain and impaired function.

Modern technological advances have made computer assisted knee replacement surgery extremely popular around the globe. In this surgery, the surgeon is assisted by a computer to remove the optimum amount and angle of the bone, which otherwise is done by inspecting manually. This is an excellent example of surgery through small incision and it eliminates the chances of human error. A perfect alignment and balance is achieved and hence longevity is also increased to 20 - 30 years. Knee replacement surgery is also specific to gender as the anatomy of male and female patients is different.

There are many types of knee replacements, most common being the total knee replacement or Total Knee Arthroplasty. In addition, there is partial knee replacement, bilateral knee replacement, revision knee replacement and knee arthroscopy.

In knee replacement surgery, the worn out surfaces of joints of knee are replaced with artificial implant of plastic and metal. The lower end of the femur bone is removed and replaced with a metal shell. The upper end of the lower leg bone (tibia) is also removed and replaced with a channelled plastic implant with a metal stem. A plastic ball is also added under the kneecap depending on its condition. These artificial components are commonly referred as prosthesis. The design of these highly flexible implants replicate knee, with the rotating knee replacement implants assist in backward and forward swing of the legs.

Patients whose knee joints have been damaged by either trauma or progressive arthritis should consider total knee replacement surgery. Post-surgical hospital stay after knee joint replacement is usually three to five days. The surgery has a very high success rate and shows dramatic improvement after a month. This improvement is most notable one month or more after surgery. The pain caused by the damaged joint is reduced significantly when the new gliding surface is constructed during surgery. Initially, patient will walk with the help of a walking aid until the knee is able to support full body weight. After six weeks, patient can walk comfortably with minimal assistance. Patients with artificial joints are prescribed to take antibiotics during the course of any elective invasive procedures including dental work. Physiotherapy is an essential part of rehabilitation and it will increase the muscle strength and patient can enjoy most activities, except running and jumping.

Knee Replacement

The shoulder is one of the most intricate joints in the body and given that it is subjected to a lot of lifting and movements, there are chances for it to tear or dislocate. The shoulder is a ball-and-socket joint with the socket in the shoulder, and the ball in the upper arm. The joint space between the two bones is surrounded by cartilage, and the space between the two is filled with fluid. Especially in athletes, due to forceful movement, this joint could get dislocated or the cartilage could tear.

The Bankart lesion is when there is a tear of the cartilage in the central anterior shoulder. This causes the cartilage to be damaged, allowing the humeral head to slip down from the socket. When the arm is extended down or to the side, it is commonly dislocated. This can happen posteriorly also, but this movement and so the injury is less likely than an anterior dislocation. If there is also a fracture of the shoulder bone with this dislocation, then it is known as bony or osseous Bankart lesion.

Causes: Bankart lesions can be acute or chronic. Acute is when there is sudden dislocation due to sports activity or accidents. Repetitive use of the shoulder can also lead to chronic Bankart lesions. This is usually seen in sportspersons like swimmers, tennis players, and weightlifters.

Signs and Symptoms:

Pain: The most common symptom with Bankart is shoulder pain that restricts any kind of movement. One may find it difficult pick up things or lifting your hands and in some cases, it is difficult to even sit straight.
Weakness: The shoulder feels weak and one is unable to perform normal activities
Instability: One may lose the grip and strength.
Limited movement: The range of motion of the shoulder may be reduced compared to before the injury.
Crackling: The damage to the fibrous cartilage produces a crackling sound, which can be heard during the movement of the shoulder.
Diagnosis: A combination of symptoms, physical examination, X-ray, and MRI can help in confirming the diagnosis.

The course of treatment depends on the cause and condition of the patient. An exercise regimen is prescribed as the first step in the treatment process. If there is inadequate progress, or if the pain seems to be recurrent, open or closed shoulder surgery may be recommended to include the following:

Arthroscopy (closed surgery) to repair the cartilage damage
Ligament re-attachment
Bone reshaping
Cartilage build up and reshaping
Ligament repair to improve stability
Any of these shoulder surgeries would be followed up with measures to reduce further injury. It is therefore advised to visit a doctor in case of any such discomfort as he/she will be able to find out the severity of the situation and devise a treatment plan accordingly.

Bankart's Lesion - What Exactly Is It?

Knee replacement can be extremely painful. Previously, opioids or narcotics were administered for pain relief. But excessive addition of opioids is not exactly effective for controlling pain. 

Multimodal pain management has become an important part of the perioperative care of patients undergoing total joint replacement. The principle of multimodal therapy is to use interventions that target several different steps of the pain pathway, allowing more effective pain control with fewer side effects. Many different protocols have shown clinical benefit. The goal of this review is to provide a concise overview of the principles and results of multimodal pain management regimens as a practical guide for the management of joint arthroplasty patients.

Multimodal denotes administering two or more than two types of medications that work with different mechanisms. The following are the techniques used:

Pre-operative Femoral Nerve Block: Prior to the surgery, a catheter is placed beside the femoral nerve for blocking it. This nerve is located in the upper thigh. Medication is delivered through the catheter for the nerve to be numbed for 24 hours. Thus, pain signals to the brain are blocked. This method reduces the use of narcotics and the consequent side effects.

Patient Controlled Analgesia (PCA): This method is also known as  Pain Pump . An intravenous pump is used to administer pain relief medications, such as oxymorphone or morphine, after the surgery. The control button of the machine could be pressed, by the patient for 6 to 10 times per hour. The machine is used for two post-operative days.

Oral Medications: The oral medications include Non-Steroidal Anti-Inflammatory drugs or NSAID; such as Celebrex which is similar to aspirin, structurally. Alternatively, acetaminophen, such as Tylenol or its equivalent composition, can also be used.

Acetaminophen: It acts on the Central Prostaglandin Synthesis and relieves the patient of pain through multiple mechanisms.

Epidural Analgesia: It produces lower pain scores and involves less time for achieving physical therapy goals. However, this is subject to side effects such as dizziness, urinary retention and itchiness.

Gabapentinoids: These medications include membrane stabilizers such as Gabapentin and Pregabalin.

The objective of multimodal treatments is to provide quick relief to the patient and immediately so. Earlier the rehabilitation, more successful will be the knee replacement surgery.

Multimodal Pain Relief After Total Knee Replacement

It is normal and alright to feel pain in the knees occasionally after a physical activity or prolonged walking. However, it is a serious cause of concern if the pain is experienced every now and then. Not responding to your knee pain for long can lead to the extreme disability. Knee pain does not crop up in a day and it may surprise you when it first appears. 

Initially, you may notice slight pain and discomfort. If you have identified knee pain at this level, managing it is easy. You can perform different exercises to prevent pain from occurring. If the pain severe, you need to go consult a doctor, who will then help identify the real cause of pain. The following exercises, along with medications, can help you overcome knee pain and restore the mobility of the joint.

Stair Step ups: Choose a comfortable stairway. Place your hand on the wall or banister. This is to ensure that you are balanced. Your left foot should be on the taller step. Your right foot should be on the ground. Stay in this posture for a second. Now, step back, and bring left foot to the right foot. Repeat this 6 times. Reverse the legs and continue doing for 6 times. If you want to take rest between the steps, feel free to do so.
Ups and Downs: You need an armless chair that is strong. Sit on the edge but comfortably. Your arms should be at your side, relaxed and loose. Sit erect and your feet should be flat. If you feel you need balance, and then cross your arms. Start standing up. This should not be instant but deliberate, controlled, and gradual movement. Stand slowly up to the full height, and hold on for 2 seconds. Again sit down. Repeat this 5 times.
Straight Leg Raise: This can be a part of your everyday exercise regime. This is a strengthening workout that does not put too much effort on the knees. Lie down on your back. One leg should be straight on the ground and the other one should be bent. Now, slowly lift the leg that is straight, and the toes should point upward. Raise your leg up to 30 degrees, but you can start with 15 to 20 degrees in the initial stage. Repeat 15 times and perform at least 3 sets of this exercise. Keep alternating legs. This workout strengthens the knees, thigh muscles, and the ankle joints, thus offering multifold benefits.
Wall Hamstring Stretch: Hamstring muscles too can be the cause of knee pain and discomfort. To strengthen the hamstring muscles and alleviate knee pain, this exercise helps a lot. Lie down on the floor flat. Your feet should be flexed. Choose a space that is close to a wall, or a sturdy table. Your right leg should be propped on the wall or table. If you don t prefer any, a resistance band is a good alternative. When stretching, you can find your flexibility level and when you feel that you have reached the deepest point, start relaxing. Keep alternating contracting and relaxing every 5 seconds. After 10 to 15 sets, you can try the same with the left leg.
Knee Rolls: Use an exercise mat or a carpet that is cozy. Lie on your back. Bend the knees, and ensure your feet are flat. Your arms should be stretched on the sides. Look at the ceiling, and hold the knees together. In the same posture, slowly roll the knees towards the right. When you feel a gentle twitch or after 5 seconds, move to original position. Then lower the knees to the left. Hold and release. For each side, repeat 10 times.
These exercises strengthen the knees and improve the quality of life by bidding bye to the pain. Understanding that these are magic remedies that work overnight is the key to stay focused and keep going without quitting.

Exercises That Can Help Relieve Knee Pain!

Pregnancy places a lot of demand on the expectant mother. While the emotional demands are not very evident, the physical ones are. The mother has to ensure that the developing baby gets all the required nutrients through her. Some of them are very critical, and not getting adequate amounts of these manifest as problems, which cannot be rectified later. Calcium supply and associated problems that may arise is one such example.
If there is a reduced supply of calcium and the bones and teeth are not formed properly, taking any amount of calcium is not going to correct the situation later, after delivery.

The bones which are forming in the developing baby are dependent on the mother for adequate supply of calcium. It is common knowledge that calcium is an integral component of bones, teeth, and skeleton. Hypocalcemia, which is a condition where there is reduced amounts of calcium in the body, can be quite severe during pregnancy.
In addition to the growing baby s needs, calcium also plays a vital role in the pregnant mother for muscular contractions, nerve conduction, hormone secretion, and blood clotting. So adequate intake of calcium during pregnancy is essential.
Now, the question arises as to how much calcium is good enough. For a normal female, about 1000 mg of calcium is required on a daily basis. This goes up by another 200 to 300 mg for a pregnant woman, especially during the third trimester when the bone and teeth formation is in full speed. This extra amount of calcium should be continued even after pregnancy, as calcium continues to be provided to the baby during the lactation phase.

Some of the symptoms of reduced calcium intake during pregnancy are aching muscles, brittle nails, weakened bones, severe cramping, and dry skin. If there is suspected hypocalcemia, it is best to seek medical advice. It is not advisable to take supplements without medical supervision. Increased amounts of calcium can produce a different set of symptoms.

While these are evident symptoms, there are other detrimental effects on the baby too. Calcium deficiency affects development of heart and associated structures and puts the newborn at a higher risk of developing hypertension. The baby s fat percentage and triglycerides are also increased. The bone mineral density is reduced. The delivery period could be prolonged, as muscular contractions and nerve conduction are severely impacted when there is less calcium in the system. Recovery from labor is also delayed.

It is possible that you are taking adequate amounts of calcium, but its absorption is affected. Reducing caffeine intake helps in better absorption of calcium. Iron, which is often given during pregnancy, prevents calcium absorption and so needs to be spaced out.

Calcium & Bone Disorders - How to Know If Your Are Suffering From Them?

Clubfoot is a deformity of the foot in infants. The condition is usually present from birth. This happens when the tissues linking the muscles to the tendons are shorter than usual, as a result of which the infant s foot appears twisted and out of shape. The condition can be mild or severe, depending on the symptoms. Often times, babies who are born with clubfoot have it in both the legs.

How to identify if your child has clubfoot?

Since the condition is present from birth, the symptoms are also easily observable. Identifying the following signs can help detect if your child is born with clubfoot-

  A foot that turns downward and inward and toes that point towards the opposite foot
  The affected foot may appear half an inch shorter than the normal foot size
  The heel of the affected foot may be smaller in size than it normally should be
  The calf muscle on the affected leg will be underdeveloped (appear slightly smaller)
  If the condition is severe, the foot may be twisted upside down

Despite its unusual shape, clubfoot does not cause pain or discomfort. The doctor will most likely notice the symptoms after the infant s birth. He/she will recommend appropriate treatment of the condition, or refer to an orthopaedic who specializes in muscle and bone ailments.

What is the treatment of clubfoot?

Clubfoot is curable so parents need not worry about their child living with a lifelong deformity.

Depending on the severity of the condition, the orthopaedic will either use devices, resort to stretching methods, or will recommend surgery.

  Ponseti Method (stretching and casting) - It is the standard treatment worldover. It starts at birth or anytime within two weeks of age and has best results in younger kids. It involves stretching the clubfoot and casting it in correct position several times over the months to restore the foot shape.
  French Functional Method (stretching and taping) - The doctor will stretch the affected foot and tape it in position several times over a couple of months to realign the shape. It, however, has very limites following.
  Surgery - Surgeries may be needed in older neglected kids or adults. The surgeon performs a surgical procedure (Achilles tenotomy) to lengthen the tendon of the clubfoot and realigns the joints and bones. Following the surgery, the child will need to be in a cast for about 2 months. Further, to prevent the recurrence of the condition, the child will be advised to wear braces for a year at least.
  Devices - They are adjunctive maintenance devices which are used by doctors in treatment of clubfoot. They are applied to the body to stabilize and limit or protect the movement of the damaged joint.

Parents should seek medical intervention if their baby is born with clubfoot. If the condition is not treated early, the child may face difficulty walking, or may even develop other disorders affecting the joints, like arthritis.
